What Is It? • Systematic method for naming ionic compounds • Monoatomic ion – one made of only a single atom Al3+ Na+ Cl- O2- • Polyatomic ion – ion made of group of covalently bonded atoms NO3- CO32- NH4+
In ionic compounds each different ion is given a name – Ion Chart The ions combine so that their charges balance
Examples • What is the formula of cobalt flouride? • What is the formula of cuprous carbonate? • What is the formula of iron (III) hydroxide?
Examples What is the name of Cr2(CO3)3? What is the name of FeCl2?
